[PATCH 03/10] fbdev: s1d13xxxfb: use resource_size

[Julia Lawall <Julia.Lawall@inria.fr>]

Use resource_size rather than a verbose computation on
the end and start fields.

The semantic patch that makes these changes is as follows:
(http://coccinelle.lip6.fr/)

<smpl>
@@ struct resource ptr; @@
- (ptr.end - ptr.start + 1)
+ resource_size(&ptr)
